Minyari Dome Project

The 100%-owned Minyari Dome Project area covers 877 km2 and features a geological structure referred to as Minyari Dome, which hosts the Minyari and WACA deposits.

In May 2022, an updated Minyari Dome Mineral Resource Estimate (MRE) was announced. The Minyari Dome combined Mineral Resource now contains 1.8 million ounces of gold, 64,300 tonnes of copper, 584,000 ounces of silver and 11,100 tonnes of cobalt.

In August 2022, the Company announced the key outcomes of the Scoping Study completed on the Minyari Dome Project. The Scoping Study identifies a potential stand-alone gold mining and processing operation at Minyari Dome. It presented the preliminary evaluation of such a development at Minyari Dome based on the May 2022 MRE. Key highlights of the Scoping Study included:

  • Initial combined open pit and underground mining inventory of 21.4 Mt at 1.6 g/t gold for 1.1 Moz.
  • 7+ years initial processing life at nameplate 3 Mtpa throughput.
  • Simple, non-refractory metallurgy allows standard CIL process plant with 90% average gold recovery.
  • Total initial gold output of 975 koz, with an average of 170 koz p.a. for the first five years.
  • Forecast average AISC of A$1,475/oz (US$1,062/oz).
  • Total pre-production capital cost of A$275M (includes pre-production ore and waste mining of A$68M).
  • Pre-tax NPV7 of A$392M and 34% IRR (at US$1,750/oz gold and 0.72 A$/US$).
  • Post-tax NPV7 of A$278M and 29% IRR (at US$1,750/oz gold and 0.72 A$/US$).
  • Post-tax payback of approximately 2.5 years from first production.
  • Latent potential to boost project economics with resource upside and by-product opportunities.

Minyari Dome Project Location Map

The Paterson Province geological setting of the Minyari Dome deposits is Proterozoic-aged, predominantly meta-sediment hosted intrusion related vein, breccia and replacement style precious and/or base metal mineralisation. Local controls on mineralisation commonly involve variations in both the competency/hardness and chemical composition of rock units, in combination with other “discrete” structural and intrusion controls.

At the Minyari deposit during 2021 mineralisation was discovered immediately east, west, and both up plunge to the southeast and down plunge to the northwest, including significant high‐grade breccia style gold-copper mineralisation.

In February 2023, Antipa regained sole rights to the Tetris, Pacman and Pixel tenements and greenfield targets (previously part of the Wilki Farm-in Project with Newcrest). Following the transaction, Antipa’s 100% controlled land holding in the Paterson Province was boosted to approximately 877km2 (previously 144km2).

Minyari

Minyari high‐grade gold-copper mineralisation is commonly associated with sulphide matrixed breccia zones similar to the Havieron gold‐copper style of mineralisation, with Minyari drilling at depth confirming continuity of moderate northwest plunging “pipe” like high‐grade breccia mineralisation down to almost 800 metres.

Mineralisation at Minyari starts at 0-10 metres from the surface and extends for more than 670 vertical metres. The mineralised corridor extends over 500 metres in length and up to 300 metres in width and remains open in several directions providing material resource extension upside.

Minyari contains an Indicated and Inferred Mineral Resource of 28.3 million tonnes grading 1.7 g/t gold, 0.2% copper, 0.6 g/t silver and 0.03% cobalt for 1.5 million ounces of gold, 56,300 tonnes of copper, 537,000 ounces of silver and 9,610 tonnes of cobalt.

 

WACA

The mineralisation at WACA is located just 700 metres south-west of Minyari and starts at 0-20 metres from the surface, extends for more than 510 vertical metres over a strike length of more than 650 metres and up to 100 metres in width. The deposit remains open in several directions providing resource extension upside.

WACA contains an Inferred Mineral Resource of 4.9 million tonnes at 1.2 g/t gold, 0.11% copper, 0.2 g/t silver and 0.02% cobalt for 192,000 ounces of gold, 5,600 tonnes of copper, 27,500 ounces of silver and 1,170 tonnes of cobalt.
